In last Thursday’s GOP debate, Marco Rubio, Ted Cruz, Jeb Bush and Chris Christie managed to avoid mentioning their common proposal to “reform entitlements” by raising the Social Security retirement age from 67 to 70. That was probably a good idea. Their proposal only demonstrates their lack of understanding about the demographics of older Americans, especially the dramatic disparities in their life expectancy associated with education and race. Recent research on life expectancy indicates that their proposed change would effectively nullify Social Security for millions of Americans and sharply limit benefits for many millions more.. While many people in their 30s and 40s today can look forward to living into their 80s, the average life expectancy for the majority of Americans who do not hold a college degree hovers closer to 70, or the average life expectancy for all Americans in 1950.

The Widening Inequalities in the Life Spans of Americans

This research, summarized recently in a study published in Health Affairs, found that life expectancy for various age cohorts of Americans is closely associated with both educational achievement and race. For example, the average life expectancy for college-educated American men who were age 25 in 2008, or age 33 today, is 81.7 years for whites and 78.2 years for blacks. (Table 1, below) By contrast, the projected, average life span of high-school educated males, also age 25 in 2008 or 33 today, is 73.2 years for whites and 69.3 years for blacks. Women on average live longer than men; but similar disparities based on education and race are evident. The average life expectancy of women age 25 in 2008, or 33 years old today, was 79 years for whites and 75.4 years for blacks for those with a high school diploma, and 84.7 years for whites and 81.6 years for blacks with college degrees. Most disturbing, the average life expectancy of Americans age 25 in 2008 without a high school diploma is just 68.6 years for white men, 68.2 years for black men, 74.2 years for white women, and 74.9 years for black women. Surprisingly, the researchers found that Hispanics in this age group have the longest life expectancies, even though they also have the lowest average levels of education. Since these data are anomalous and may reflect sampling problems, we will focus mainly on the life-expectancy gaps between African American and white Americans.

Tallying How Many People Are Adversely Affected

Census data on the distribution by education of people age 25 to 34 in 2010 (ages 30 to 39 in 2015) provide a good estimate of how many Americans are adversely affected by these growing differences. Overall, 56.3 percent of all Americans currently in their 30s fall are high school graduates or left school without a high school diploma, educational groups with much lower average life expectancies. (Table 2, below) More precisely, 10.1 percent or almost 4.8 million Americans in their 30s today lack a high school diploma, and 46.2 percent or 18.9 million thirty-somethings have high school diplomas and no further degrees. All told, they account for 23,702,000 Americans in their 30s; and among older Americans, the numbers and percentages are even higher.

Since race as well as education are major factors associated with differences in life expectancy, we turn next to education by race (Table 3, below). The totals differ modestly from Table 2, because Census data on education by race cover ages 30-39 in 2014, while Table 2 covers age 30-39 in 2015 (ages 25-34 in 2010).

• Among people in their 30s today, 45.4 percent of whites or 10,613,000 Americans have a high school degree or less – and their average life expectancy is 9.4 years less than whites in their 30s with a college or associate degree.
• Among people in their 30s todays, 64.4 percent of blacks or 3,436,000 Americans have a high school degree or less – and their life expectancy is 8.6 years less than blacks in their 30s with an B.A. or associate degree, and 11.6 years less than whites with a college or associate degree..
• Among people in their 30s today, 75.6 percent of Hispanics or 6,243,000 Americans have a high school degree or less – and their life expectancy is 5.0 years less than Hispanics in their 30s with a college or associate degree.

As a policy matter, these data tell us that across all communities—white, black, Hispanic—improvements in secondary education to prepare everyone for higher education, and lower-cost access to higher education, can add years to the lives of millions of Americans.

Preserving Meaningful Access to Social Security Benefits

The widening inequalities in average life expectancy associated with race and education have more direct policy implications for Social Security, because the number of years that people can claim its benefits depends on their life spans. The growing inequalities in life expectancy translate directly into growing disparities in the years people can claim Social Security benefits, based on their education and race. Assuming that Americans in their 30s today retire at age 67 (the age for full benefits for this age group), they can expect to claim retirement benefits, on average, ranging from 1.2 years to 19.3 years, based on their education and race. (Table 4, below)

The most pressing issues of life expectancy and Social Security involve white males, black males, and black females without college degrees: Among Americans age 33 today, white and black men without high school diplomas and black males with high school degrees, on average, can expect to live long enough to collect benefits for less than three years. Similarly, white and black women without high school diplomas and black women with high school degrees, on average, can expect to collect benefits for less than eight years. Together, they account for 25.2 percent of whites and 64.4 percent of blacks in their 30s today. By contrast, male and female white college graduates age 33 today, on average, can expect to collect Social Security for between 14.7 and 17.7 years, respectively; and 33-year old black men and women with college degrees, on average, will claim benefits for 11.2 to 14.6 years, respectively.

These findings dictate that proposals to raise the Social Security retirement age should be rejected as a matter of basic fairness. Among this year’s presidential hopefuls, as noted earlier, Ted Cruz, Marco Rubio, Jeb Bush and Chris Christie all have called for raising the retirement age to 70 years. Under this policy, black men in their 30s today without a college degree and white men now in their 30s without a high school diploma, on average, would not live long enough to collect any Social Security. The change would reduce the average number of years of Social Security for Americans in their 30s today,

• From 1.6 years to -1.4 years for white men with no high school diploma,
• From 1.2 years to -1.8 years for black men with no high school diploma, and
• From 2.3 years to – 0.7 years for black, male high-school graduates.

Furthermore, among Americans in their 30s today, white and black women without a high school diploma, white male high school graduates, and black female high school graduates, would live long enough, on average, to collect Social Security for just 3.2 to 5.4 years. The GOP change reduce the average number of years of Social Security for Americans in their 30s today,

• From 6.2 years to 3.2 years for white, male high school graduates,
• From 7.2 years to 4.2 years for white women with no high school diploma,
• From 7.9 years to 4.9 years for black women with no high school diploma, and
• From 8.4 years to 5.4 years for black, female high-school graduates.

All told, proposals to raise the retirement age to 70 years old would mean, based on the average life expectancy of Americans in their 30s today, that 25.2 percent of whites in their 30s and 64.4 percent of blacks of comparable age, after working for 35 years or more, would receive Social Security benefits for 5.4 years or less.

Midway through Hong Kong’s second public consultation on the method of electing the next chief executive (CE), both pro-democracy “pan-democrat” legislators and the Hong Kong government and Chinese Central government are still holding their cards close. Following the current public consultation, members of Hong Kong’s Legislative Council (LegCo) will cast an historic vote on political reform. Hong Kong’s mini-constitution, the Basic Law, states that “the ultimate aim is the selection of the CE by universal suffrage upon nomination by a broadly representative nominating committee in accordance with democratic procedures” (Basic Law Art. 45). Pan-democrat LegCo members currently plan to vote against the eventual resolution on political reform, given their dissatisfaction with the reform process to date. Observers predict that passage of a resolution will happen only if the Hong Kong and Central governments can swing a few pan-democrats over to their side in the final hour.

The problem is a prickly one: Is it possible to design an electoral system that is sufficiently open and democratic in the eyes of the Hong Kong people and, at the same time, that guarantees to the Central Government that the elected leader of this special administrative region accepts the supremacy of the Chinese Communist Party? Even as politicians on each side reiterate the near “impossibility” of changing their positions (see e.g., RTHK Backchat discussion with Justice Secretary Rimsky Yuen at 4:25), thought-leaders from Hong Kong’s universities are inventing creative proposals with the potential to break the deadlock.

The Ground Rules

A 2004 decision of the Standing Committee of the National People’s Congress (NPCSC), China’s national legislature, interpreted the Basic Law to require a “Five-Step Process” in order to amend the selection method for the CE. Hong Kong is now between Steps 2 and 3.

• Step 1: The current CE must submit a report to the NPCSC on the need to amend the electoral system. That submission took place on July 15, 2014 after a five-month initial public consultation process. The CE’s report faced heavy criticism in Hong Kong for not accurately reflecting public opinion.
• Step 2: The NPCSC must issue a decision affirming the need for the amendment. The NPCSC announced that decision on August 31, 2014. It endorsed a system by which citizens may directly vote for the CE but imposed restrictive conditions on the nomination procedure of eligible candidates. The decision triggered 79 days of protest and civil disobedience – what activists and the media have referred to as the “Umbrella Movement.”
• Step 3: The Hong Kong government must introduce the political reform bill in LegCo, and two-thirds of legislators must endorse it. The vote in LegCo is scheduled to take place during the first half of 2015, although a precise date has not been set. The purpose of the second-round public consultation is to forge consensus behind political reform within the parameters set out in the August 31 NPCSC decision.
• Steps 4 and 5: In the event that LegCo endorses the bill, the CE must provide his consent and report the amendment to the NPCSC for its final approval.

If the bill does not receive two-thirds endorsement of LegCo (or if it does, but the NPCSC does not approve) then political reform would fail. Hong Kong would be left with the status quo, and Hong Kong people would lose the opportunity to vote for their chief executive for at least the next seven years.

Limited Room for Negotiation

The terms set out by the August 31 NPCSC decision limit the range of possible political reform options. For that reason, one of the core demands of the Umbrella Movement was to scrap the decision and re-start the Five-Step Process; that didn’t happen, however. In January 2015, the Hong Kong government issued a public consultation document framing the discussion in the lead up to the vote in LegCo. The consultation document hews closely to the NPCSC decision:

• The Nominating Committee (NC) will resemble the previous committee that elected the CE with the same number of members (1,200) belonging to the same limited number of subsectors (38). The Wall Street Journal recently described that committee as “a hodgepodge of special interests.” During the consultation, citizens may discuss adding new subsectors to make the committee more inclusive and representative (such as adding new subsectors to represent the interests of women or young voters), but restructuring will necessarily mean disrupting and eliminating the positions of existing subsectors or committee members. Therefore, the consultation document suggests these changes are unlikely to be achieved (Consultation Document, Chapter 3, Sec. 3.08 p. 10).
• The NC will nominate two to three candidates, and each candidate will require endorsement from at least half of the NC membership. (Given the difficulty of restructuring the subsectors or their electoral bases, these terms would effectively exclude any pan-democrats from nomination.) In order to make this more palatable, the consultation document proposes that citizens discuss a two-stage nomination process. In the first stage, a quorum of 100-150 committee members would “recommend” individuals for nomination. The committee would then elect the nominees from this recommended group (Consultation Document, Chapter 4, Sec. 4.09 p. 14). In theory, the meetings when recommendation and nomination votes take place could be staggered in order to allow campaigning and public debate. The idea is that NC members would take public opinion into consideration before casting their second vote.
• On the voting arrangements, citizens may discuss a “first-past-the-post” arrangement with either a single-round, two-round, or instant runoff vote systems (Consultation Document, Chapter 5, Sec. 5.06 p. 17-19).

Both sides in this negotiation have fired shots across the bow. At the launch of the second public consultation on January 7, Chief Secretary Carrie Lam remarked, “there is no room for any concessions or promises to be made in order to win over support from the pan-democratic members.” For their part, the pan-democrats vowed to boycott the public consultation and veto a resolution that conforms to these terms. They argue that the proposed method of electing the chief executive does not improve upon the status quo.

Most pan-democrat legislators are directly elected from geographical constituencies, and public opinion could provide legitimate grounds for shifting their position. According to polling by the Hong Kong University Public Opinion Programme last month, a plurality of respondents view the Hong Kong government’s proposal as neither a step forward nor a step backward for democracy. If the government were to commit to making the electoral system more democratic in the next CE election in 2022, a clear majority of respondents would then support the government’s plan.

Inventing Options and Finding Common Ground

The two-stage nomination mechanism in the government’s proposal is an acknowledgement that the NC ought to be responsive to public opinion. But without additional tinkering, this procedure does not materially change the incentives of NC members. What if the public had the power to reject the slate of candidates nominated by the committee?

Since the first public consultation, a few academics, including Simon Young at Hong Kong University (HKU), have considered at least two ways this could happen. An “active” approach would allow Hong Kong voters to cast blank votes and require a minimum percentage of affirmative votes for the winning candidate. A “passive” approach would require a minimum voter turnout rate for a valid election. NC members might then have to take public opinion into account.

Early last month, Albert Chen, also a professor at HKU and a legal advisor of the NPCSC, began to advocate publicly for a proposal that employs a ballot with a none-of-these-candidates option (see RTHK Jan. 13 edition of The Pulse). Under his proposal, if a majority of people vote for “none-of-these-candidates,” the slate of candidates put forward by the NC will be voided. When the public votes down the candidates, the NC could revert back to an election committee and choose a provisional CE. Alternatively, the Chief Secretary could assume CE duties during a six-month interim period prior to a new election (drawing upon Basic Law Art. 53). Chen argues that his proposal would give the Hong Kong people—not pan-democrat politicians—decision-making power to accept the new NC and its slate of candidates or to revert back to the status quo.

More recently, Johannes Chan, HKU professor and human rights advocate, floated a competing proposal that would provide voters with the option for negative voting. A 20 percent “no” vote for an otherwise leading candidate would trigger a re-vote. Between the first and second elections, the candidates would have additional time to campaign. If after the second election, still 20 percent of voters oppose the leading candidate, the candidate would be disqualified, and the NC would nominate new candidates. Given Hong Kong’s governance problems and increasing public polarization, the 20 percent veto ensures that no CE will be saddled with a substantial block of Hong Kong society affirmatively opposed to him or her from day one.

Albert Chen’s proposal received a tepid if supportive response in pro-Beijing quarters. Jasper Tsang, the Speaker of LegCo and member of the largest pro-establishment political party, and Rita Fan, a member of the NPCSC, affirmed their view that the none-of-these-candidates mechanism does not violate the Basic Law. While the government’s consultation document does not expressly mention the none-of-these-candidates concept, Hong Kong’s Justice Secretary indicated that the proposal should be considered. Starry Lee, another leader of the biggest pro-establishment party in LegCo, countered that technical difficulties and limited time for discussion would pose obstacles to the none-of-these-candidates ballot proposal.

Pan-democrats so far have tended to rebuff government overtures to engage on the topic. A few legislators, such as the Civic Party’s Ronny Tong, have been willing to engage (with Albert Chen on the Jan. 13 edition of The Pulse) but have reservations about what happens after a voided election, and feel that the threshold for public veto is too high. Law Chi-kwong, a founding member of Hong Kong’s Democratic Party and also a member of the HKU faculty, suggested that the winning candidate ought to receive an absolute majority of votes with blank votes counted. (E.g., when one candidate receives 45 percent, another receives 35 percent, and none-of-these-candidates receives 20 percent, that would lead to a void election.) However, other scholars associated with the Democratic Party have distanced themselves from the blank vote debate and Law’s statements.

The Merits of Blank Voting

The debate over blank and negative voting in Hong Kong unfolds in a global context where none-of-these-candidates has become an increasingly common political choice. Several democracies have institutionalized the practice. Proponents cite instrumental rationales, such as improved accountability and transparency. However, these benefits are not necessarily guaranteed. More broadly, people recognize the inherent value of the “no” vote as a form of political expression.

In the U.S. state of Nevada, for example, a none-of-these-candidates option has appeared on the ballot for all statewide and national elections since 1975. During the 2012 presidential cycle, the Secretary of State of Nevada argued that removing a none-of-these-candidates option would harm Nevada voters by taking away a “legitimate and meaningful ballot choice.” There is precedent for none-of-these-candidates winning a plurality of votes in a congressional primary; in that case, Republican Walden Earnhart finished behind the none-of-these-candidates option but still “won” the primary and got the nomination. More typically, the ballot option plays a “spoiler role.” In the 1998 Senate race, for example, 8,125 votes for none-of-these-candidates dwarfed the 395-vote margin between Harry Reid and John Ensign. This allowed Reid, the incumbent, to be re-elected.

It is hard to find examples where none-of-these-candidates has won a majority of the popular vote. Hong Kong’s pan-democrats may be right to question whether this possibility would meaningfully affect the calculus of the NC. Colombia is one of the few jurisdictions where blank votes can have institutional consequences. The right of citizens to cast a blank vote was established by the Colombian Constitution in 1991, and later codified in political reform statutes in 2003 and 2009. Similar to Albert Chen’s proposal in Hong Kong, if the number of blank votes equals a majority of the total number of votes cast, the election must be repeated. The original candidates cannot participate in the second election.

The Colombian experience suggests that the blank vote is more consequential in races with fewer candidates. Colombian voters have never nullified a slate of candidates at the national-level, where the field is crowded. In the city of Bello, however, the blank vote won the mayoral election in 2011. In that case, the electoral authority disqualified the one opposition candidate. This led to a one-man race and united all opposition forces around the blank vote in order to reject the establishment Conservative Party candidate. In the second round election, the replacement Conservative Party candidate (Carlos Alirio Muñoz López) won 59 percent of the vote. In the end, his party benefited with a resounding popular mandate. By this logic, the blank vote could matter in the two- to three-candidate race contemplated for Hong Kong.

Empirical evidence also suggests that local conditions in Hong Kong could support a relatively high turnout for none-of-these-candidates. Based on data from Spain and Italy, Chiara Superti at Harvard finds that blank voting is a sophisticated political choice, more likely to take place in municipalities with highly educated and politically engaged electorates. Hong Kong would qualify.

Beyond candidate selection, voting is a highly expressive act. A citizen’s vote is an expression of identity as well as a channel for protest. Echoing this view, the Supreme Court of India recently held that the country’s constitutional guarantees of freedom of speech and expression confer on Indian citizens a right to reject all candidates and to exercise their right to affirmatively vote for none-of-these-candidates in secrecy. As a people who define themselves by “core values,” including freedom of expression, this resonates with Hongkongers. More fundamentally, the ballot serves a powerful safety-valve function. At the time universal suffrage was introduced in England and France, the vote was presented as a way to channel political turmoil into more moderate political expression—and this, too, resonates in Hong Kong today.

*A slightly modified version of this commentary appeared in the St. Louis Post-Dispatch on October 19, 2004.

So it looks like Missouri's gubernatorial race will turn on "character" issues.

GOP consultant Paul Zemitzsch predicts Secretary of State Matt Blunt will portray Claire McCaskill, the Democratic state auditor, as "an extra-liberal female candidate" and "waffler" when things get ugly. McCaskill, for her part, has already countered one attack on her "hypocrisy" with her own attack on Blunt's veracity.

Look for more talk about character as Election Day approaches.

Yet that would be too bad.

Missouri needs to talk about some other things this fall.

In a recent statewide report, "Growth in the Heartland: Challenges and Opportunities for Missouri," for example, we argued that Missouri faces a land-use and competitive crisis that demands serious attention.

The crisis is not new—we described it two years ago—but the fact remains that Missouri's chaotic style of low-density development is defacing the state's rural heritage, gutting towns and cities, and exacting a heavy toll on Missourians' pocketbooks and quality of life just when the state needs to compete at a higher level on those factors.

Just look around:

Strip malls and home sites chewed across nearly 350 square miles of Missouri prairie and fields in the 1990s as sprawl engulfed rural Missouri and the state continued to develop land almost four times as fast as it's been adding population.

Cities are struggling, as fast exurban growth either outstrips city and town growth or, in the case of St. Louis, drains the center-city of vibrancy.

And recently decline has spread beyond the state's big urban centers into numerous older suburbs, so that inner-ring municipalities like Wellston and Rock Hill in the St. Louis area, or Raytown and Grandview near Kansas City, now suffer from population losses.

Why do these trends matter? For some the concern is cultural. They fear the state is losing its rural ambiance. For others the threat is environmental. They know scattershot development is tainting the Ozark lakes and degrading Missouri's natural areas.

However, for us the concern is mostly economic: By remaining virtually laissez faire on growth and development issues, we fear the Show Me State is undercutting its ability to parlay its very real assets in the life sciences and other high-value industries into a broader prosperity.

On the one hand, Missouri's dispersed development adds to the size of the state's enormous—and crumbling—highway system. Already Missouri taxpayers struggle with a maintenance backlog that will require half a billion dollars a year over the next 10 years—$200 million more than current finding will provide.

On the other, we suspect that the state's spread-out, low-quality development diminishes Missouri's appeal to the educated workers necessary to prosper in biotech, medical instruments, and infomatics. Educated workers gravitate to vibrant urban centers with plenty of amenities. Missouri's sprawl, by contrast, drives them away by draining the state's downtowns and Main Streets of life and variety.

And so we say it again: Missouri and the gubernatorial candidates need to face up to some tough realities this fall:

• Missouri can't afford to keep sprawling, even with tax revenues stronger this year. Blunt and McCaskill need to tell Missourians how they will foster more efficient, less chaotic growth that doesn't break the bank

In sum, the Show Me State stands at a crossroads.

With huge issues about their state's future livability and prosperity in the balance, Missourians shouldn't buy into a campaign focused on character issues and divisive wedge issues.

Instead, they should insist candidates Blunt and McCaskill address the state's problems head on and get to work.

This election cycle, what will separate Democrats from Republicans on energy policy and their approach to climate change? Republicans tend to be fairly strong supporters of the fossil fuel industry, and to various degrees deny that climate change is occurring. Democratic candidates emphasize the importance of further expanding the share of renewable energy at the expense of fossil fuels, and agree that climate change is a real problem—with some saying the challenge trumps most, if not all, other U.S. security concerns.

Now that there are presumptive nominees for both major political parties, it’s an important moment to outline, in broad strokes, the positions of Secretary Hillary Clinton and businessman Donald Trump. We realize that Democratic Presidential candidate Bernie Sanders has not dropped out of the race, but note that it is fairly unlikely at this point that he would clinch the nomination.

Clinton: Building on the Obama legacy 

Secretary Clinton has laid out the most comprehensive and detailed energy and climate policy proposals of the candidates to date. They are in essence a continuation, and in some cases a further expansion, of existing White House policies under President Obama. The Secretary has stated that she wants the United States to be the “clean energy superpower of the 21st century.”

This starts with the notion that climate change is an existential threat, which the global community has to address as soon as possible. In order to do that, in her view, the United States needs to continue to show leadership on the international stage, as the Obama administration sought to do surrounding the Paris agreement in December 2015. This will require substantial reforms to expand low-carbon options, including nuclear energy to some degree, while tightly regulating fossil fuels (and gradually phasing them out). 

[S]he wants the United States to be the “clean energy superpower of the 21st century.”

The first casualty of this transformation is the coal industry, which Clinton has explicitly acknowledged. She presented a $30 billion plan to revitalize communities where coal production is currently an important industry and job creator, for example, and has campaigned with this message in various state primaries. Implicitly, Secretary Clinton does not seem to believe in the economic viability of carbon capture and sequestration in the United States—this is despite the fact that most analyses, including those of the Intergovernmental Panel on Climate Change (IPCC), suggest that this technology could be a cost-efficient tool in a wider carbon emission mitigation portfolio. 

Clinton sees natural gas as a bridge fuel, though at this point it’s not clear how long that bridge is. Questions remain about the role that natural gas can play in scenarios of deep decarbonization in 2030 and beyond. At the moment, the gas industry is rather nervous of the Secretary’s statement that she’d increase regulations on, in particular, the fracking industry—if her conditions came to fruition, there would very few places where fracking would continue. 

Secretary Clinton believes that oil consumption has to be cut substantially in the coming years, and she has suggested that new drilling in places like the Arctic, off the Atlantic Coast, and on federal lands would be discouraged or banned. She has previously opposed crude oil exports, though we would not anticipate a roll-back of existing policies (in December 2015, the Obama administration lifted the decades-old ban). 

Clinton foresees a new energy economy built on rapidly increasing shares of renewable energy, which should comprise 25 percent of the U.S. fuel mix by 2025 according to her plan (solar energy would be a key focus, with half a billion panels to be installed by the end of her first term). To facilitate this transition, she presented an elaborate energy infrastructure plan to modernize the U.S. grid and improve efficiency in reviewing and approving projects. 

Tax credits to support renewables would be continued under a Clinton White House, whereas fossil fuel subsidies would be phased out. Increased energy efficiency, including harmonization of vehicle efficiency and fuel standards, are high on her agenda as well. The Secretary also supports the Clean Power Plan that the Environmental Protection Agency under the Obama administration has launched, and which is currently on hold in the Supreme Court. 

On the international stage, Clinton supports the Paris agreement on climate change. Should she win the presidency in November, she would make an effort to take this Treaty to the next step, thus continuing U.S. leadership. That would mean reinforcing U.S. leadership along the lines described above, while helping address current uncertainties about finance, transparency, and accountability, to name only a few challenges that remain.

Trump: Drill, baby, drill

Although Donald Trump’s candidacy remains highly controversial, he is now the presumptive Republican nominee for president. To the extent that we know any detailed plans, quod non, it is safe to say that his views on energy and climate change are diametrically opposed to most of Clinton’s. Broadly speaking, Mr. Trump has come out as a fervent supporter of the fossil fuel industry, and has expressed skepticism about the economic viability of renewable energy.

Mr. Trump’s views start with the belief that climate change is not man-made. In the past, the controversial businessman has suggested that climate change might be a hoax invention from China, in order to undermine U.S. industrial interests and job creation. This starting point allows Mr. Trump to be extremely supportive of existing industrial interests (if carbon and other greenhouse gas emissions are not a problem, the thinking goes, then business as usual is the way to go). 

In a speech in North Dakota in late May, Mr. Trump laid out some broad initial ideas for his energy policy. He declared that under his presidency the United States would “accomplish complete American energy independence,” leaving unaddressed arguments about what that would mean for existing international energy trade. 

It is probably safe to say that Mr. Trump would like to further expand oil, gas, and coal production in the country. The latter, in particular, is remarkable: even coal executives have declared that market forces (particularly very competitive natural gas) have been the primary threat to the coal industry. Since Mr. Trump is also a strong supporter of the natural gas industry—and considering the challenges of building new bulk terminals for exports—it is unclear how a revitalization of the coal industry would occur. 

If climate change is a hoax, it will come as no surprise that Mr. Trump will not support efforts to mitigate carbon and other greenhouse gas emissions.

Contrary to his opponent, Mr. Trump would also like to revoke restrictions on drilling for oil and gas, and would permit production on federal lands. He also supports further expansion of energy infrastructure, and would, if elected, ask Trans Canada to resubmit a permit application for the Keystone pipeline, which he’d approve. He has caveated his support for projects like these by demanding that a portion of the revenues from oil and gas flows be redistributed to local communities, to compensate them for intrusion on their private property. Mr. Trump has also indicated that he wants to use revenues from oil and gas production to rebuild U.S. infrastructure more broadly.

If climate change is a hoax, it will come as no surprise that Mr. Trump will not support efforts to mitigate carbon and other greenhouse gas emissions. The candidate has called the Obama administration’s Clean Power Plan “stupid,” and when asked what he would do about the Paris agreement on climate change, he said he’d cancel it. 

Though Trump says the United States must pursue all forms of energy—including renewables—he has expressed skepticism about their economic viability, calling solar energy “very expensive.” Wind energy received similar pejorative feedback, since Trump says it kills eagles and is noisy. During one of the few debates about renewable energy during the Iowa primary, he voiced his support for blending biofuels in vehicles. 

To the polls

The 2016 U.S. presidential election will have a profound impact on global affairs. Not only will it affect a range of security and economic issues in important ways, it also means a lot for global energy and climate policy. Will the United States continue on the trajectory that President Obama has started and continue a major energy transition strategy? Or will it shift course, potentially undermining existing domestic policies and investments, as well as international obligations? In November 2016, the American people will decide.

There's a little more than a week to go before the Democratic National Convention begins in Boston. Senator John Kerry is both raising and spending money at a furious pace. The Kerry campaign raised about $182 million from March through June. Senator Kerry also outspent President George Bush in advertising throughout most of the summer. But the president still has more cash on hand, reportedly $63 million at the end of May. That's the latest figure available. The president also has more time to spend that money before accepting his Republican nomination on September 2. Anthony Corrado is an expert on campaign finance.

Listen to the entire interview

After his first place finish in Iowa, which was supposed to propel him to a New Hampshire victory, “change” is probably a word Barack Obama does not like as much anymore. But, his support did not really change much between these two elections. He won 38 percent of Iowa’s delegates and 36 percent of New Hampshire’s vote. It was Hillary Clinton and John McCain who were the big change candidates.

What happens when a presidential candidate that does well in a primary or caucus state, does not do so well in the next? The dynamic of the presidential election can swiftly and stunningly change, as it did in New Hampshire on Tuesday.

How Barack Obama wishes John Edwards showed up in New Hampshire.

Edwards was awarded 30 percent of Iowa’s delegates, barely denying Clinton a second place finish. He finished a distant third in New Hampshire, receiving only 17 percent of the vote. There are strong indications that a shift among his supporters helped propel Hillary Clinton to her New Hampshire victory.

According to the exit polls, Edwards did 8 percentage points worse in New Hampshire among women, while Clinton did 16 percent better. Obama’s support was virtually identical, dropping a statistically insignificant 1 percentage point.

Obama’s support among young people remained strong, if slightly increasing among 18-24 and 30-39 year olds. Clinton’s support remained strong and slightly increased among those 65 and older. Edwards won Iowa’s middle-aged voters, age 40-64, but it was Clinton who decisively won this coveted age demographic in New Hampshire. And where these people were 38 percent Iowa caucus attendees, they were 54 percent of New Hampshire voters. (To understand why their turnout increased, see my analysis of Iowa’s turnout .)

Moving forward, the generational war is still a strong dynamic in the Democratic race, as evident in the candidates’ speech styles following the election results. In Iowa, Clinton was flanked by the ghosts of the Clinton administration. In New Hampshire, she shared the stage with a sea of young voters. In Iowa, Obama spoke of change, a message that resonates with younger people who are not part of the establishment. In New Hampshire his slogan was a message that echoes the can-do spirit of the greatest generation, “Yes, we can!”

In the days between Iowa and New Hampshire, Edwards spoke about how he wanted the election to become a two-way race. One should be careful with what one wishes for. Edwards and Clinton are vying for the same support base, that when united can defeat Obama, at least in New Hampshire. In the short-term, Obama most needs Edwards to do better so that support can continue to be divided.

Among Republicans, John McCain recreated his magic of eight years ago and bounced back strong from a poor Iowa showing to win New Hampshire.

The Iowa and New Hampshire electorates are so different it is difficult to compare them. In Iowa, Evangelical Christians were 60 percent of the electorate, while in New Hampshire, they were only 23 percent. Mike Huckabee’s move from first in Iowa to third in New Hampshire can be clearly attributed to the shrinking of his base. His collapse paved the way for a new winner to emerge.

It is thus tempting to attribute McCain’s victory solely to the different electorates, but he still had to defeat Mitt Romney to win New Hampshire.

According to the exit polls, the battle between McCain and Romney is a referendum on the Bush administration. Surprisingly, McCain, who has tried to rebuild bridges with the Bush establishment since his defeat in the 2000 presidential election, is still seen as the outsider and agent of change by voters participating in the Republican nomination process.

In both Iowa and New Hampshire, McCain drew his support from those who said they are angry or dissatisfied with the Bush administration. Romney drew his support from those who said they are enthusiastic or satisfied. Not surprisingly, McCain is also drawing more support from self-described Independents and Romney from Republicans.

The candidates seem to understand this dynamic, too, as they gave their speeches following the election results. In a contrived bit of acting, Romney showed up on stage without a podium and shoved a prepared speech back into his pocket (if he had needed a podium, his advance team would have provided it). He appeared relaxed, delivering his speech in a personable style reminiscent of Huckabee, who is competing with Romney for those who support Bush. But he also seemed to be reaching out to Independents with a message of change. In stark contrast, McCain delivered a carefully written, almost sedate speech designed to reassure Republicans of his conservative credentials.

This three-way dynamic between Huckabee, McCain, and Romney should prove fascinating as the Republican nomination process moves forward. Where Evangelicals are strong, Huckabee should do well. Where they are not, the rules governing if Independents can or cannot participate will dictate how McCain and Romney do. And we have yet to see regional candidates like Fred Thompson have their day in the sun. And then there is Rudy Giuliani, who is lying in wait in the larger states where his name recognition should give him a significant boost over the other candidates. All of this points to an extended campaign among Republicans.
